Yeah, 2014 wasn't really a Republican wave on the Senate level. They won all the Romney states, yes, but they barely managed to win CO against a terrible Democrat and underperformed in several Romney states. That's why this idea that 2018 is going to be a Democratic wave year in the Senate is exaggerated. I think the general trend we're seeing is that blue states are electing Democratic Senators and red states are electing Republican Senators (even though red state Democrats are still much better off than blue state Republicans).
I do not think anyone thinks 2018 will be a Democratic wave on the Senate level but I do not think every single Trump State democrat will lose either.
